Photochromic materials and room-temperature phosphorescence (RTP) are essential for applications in optoelectronics bioimaging. Organic–inorganic hybrid materials, particularly those exhibiting donor–acceptor (D–A) characteristics through supramolecular interactions, have shown significant potential to integrate both photochromic RTP properties. Among them, the anion–π π–π interactions been extensively studied; however, role of anion–π–π remains largely unexplored. This study investigated three naphthalenediimide-polyoxometalate (NDI-POM) hybrids: (H2DMAP-NDI)·(HPW12O40)·(NMP)2 (1), (HDMAP-NDI)2·(HPW12O40)·(NMP)2 (2), (HDMAP-NDI)2·(HPW12O40)·(NMP)7 (3), focusing on impact their The results indicate that 1 exhibits fastest photoresponse highest quantum yield, primarily driven by interactions. Hybrid 2, which involves shows slower photochromism lower yield due exciton localization nonradiative decay paths resulting from stacking. 3, characterized excessively strong is unstable nonemissive. provides valuable insights into offers a framework designing advanced photoresponsive with tunable properties diverse applications.
